Here's the message that dermatologists and skincare professionals want to get through to men across the globe: skincare matters.

No matter what age you are, you can benefit from developing a skincare regimen for your skin.

Why? Because it will keep your skin looking better, fresher, and younger for longer — as well as ward off irreversible sun damage.

"A lot of guys say, 'Oh I don't have time. I really don't need it.' The truth of the matter is that you do," Chris Salgardo, author of grooming and skincare guide Manmade and president of skincare brand Kiehl's, told Business Insider.

The most important thing men can do is use sunscreen daily. 

"One of the most inexpensive ways to keep your skin looking its best for the longest period of time possible is to use a sunscreen," Salgardo said.

Sun damage is cumulative, which means the sooner you work to prevent it by applying a broad spectrum sunscreen daily, the better off you'll be. 

Moisturizer is another cornerstone for men's skincare. It will, over time, lessen the appearance of wrinkles and fine lines, preventing them from settling in and making you appear older than you actually are.

It will also make your skin feel more supple and healthy, contribute to its natural glow, and help avoid that "tight" feeling your skin gets when you wash your face in the morning. Eye cream is another subset of moisturizer specially formulated for treatment of the thin-skinned eye area, where those wrinkles have a tendency to appear earlier.

To the guys who claim that they just don't have enough time to develop and maintain a skincare routine, Salgardo has just one thing to say: "That's just not true. The reality is that it's not complex. It shouldn't be daunting," Salgardo told us. "You should be able to get it done and get it done quickly."

"We're all living longer lives," Salgardo said. "Look the best at every age."

"My aunt passed away years ago, so this ornament reminds me that she will always be with us each Christmas holiday. She loved building snowmen; it was her favorite thing to do. When I hang this decoration on the tree each year, it makes me feel warm inside knowing we have a special ornament just for her." — Angela 

Birmingham, United Kingdom

"My two little sisters gifted me this special handmade star bunting ornament on Christmas Eve. They live in India, and I have not seen them since 2011 ... this gift made me realize that no matter how far apart we live, we will always be connected to one another just like this star bunting." — Gavin

Canterbury, United Kingdom

"This is a small seated porcelain bisque Santa which belonged to my late great-grandmother. I remember this decoration being locked in her ornament cabinet when I was a very small child ...The ornament now stands in my own cabinet, and I bring it out each holiday season and stand it on the bookshelf with other treasured mementos of Christmas past and present." — Lorraine

Chances are, you didn't even know that Subway served a pizza sub. 

But they do — on their secret menu, not their regular one.

However, if you do get a blank stare when you request the pizza sub, simply ask to build your own sandwich, then ask for tomato sauce, pepperoni, mozzarella cheese, and any veggies you'd like.

You'll end up with a pizza and a sandwich all in one; what more could you want?

On Monday morning, Eric Jackson, manager of hedge fund SpringOwl, sent a brutal 99-page presentation to Yahoo's board outlining his case for why the company should drop Marissa Mayer as CEO and find new management.

Among Jackson's grievances about Yahoo is everything Mayer has blown money on, from failed acquisitions to lavish parties and sponsorships.

He claims that a December 2014 party had a photo shoot that cost Yahoo $70,000 alone, and that the company's Roaring 20s-themed holiday party this year at Pier 48 in San Francisco cost $7 million. A source with knowledge of the company and the cost of the party tells Business Insider that the cost was actually less than a third of Jackson's claimed $7 million.

We've rounded up some pictures from Yahoo's lavish holiday party so you can see what it was like:

Shazop could revolutionize shopping for high-end fashion online.

It's a brand new comparison shopping site, where shoppers can select designer dresses, shoes, and handbags and from over sixty different retailers — such as Neiman Marcus, Saks Fifth Avenue, Shopbop, Nordstrom, and Macy's — and compare sizes and prices. The site keeps track of coupon codes for added discounts.

Founder Andrea Marron, former Vice President of Digital at Nicole Miller, came up with the idea during her tenure at Nicole Miller. She noticed that whenever the company would distribute product to retailers, the mark downs would vary tremendously. In spring 2013, she teamed up with ZocDoc developer Amit Sawat, and Shazop began to come to realization.

It's obviously in its nasceny, but Marron thinks of the website as the Kayak of online shopping.

"Way back in the day, you would go to ten different airline sites to try to find the best price on a flight," Marron said in an interview with Business Insider. "But now, it's a lot more convenient for a user to just go to Kayak to find the best flight. We want to be the one place that a consumer can go to to browse and find the best style for them and have all the information there for them on one page."

Right now,Shazop sells high end brands, like Tory Burch, Elizabeth & James, and Rag & Bone. This is intentional. 

"We thought that it’s easier to brand yourself as high-end and later add the lower-end brand then to do the reverse," she said. Right now, she wants Shazop to be a "curated experience." In the coming weeks, Shazop will offer more brands, including Kate Spade, Balmain, and BCBG. Shazop will continue to add products and designers as the site grows, and Marron said that a suggestion will allow users to request brands they'd like to see on the site.

Not only is this beneficial to consumers, but Marron believes that retailers can benefit from this service, because it's "an opportunity for them. Let's say someone is browsing on Shazop for a dress and it's sold out at a retail that they had in mind ... another retailer could potentially pick up a customer by having that size in stock."

It all is rooted in a tremendous amount of data. Shazop pulls data from the websites and brings the information to the consumer easily, making it a one-stop shop for consumers.

Naturally, Shazop has accumulated tons of data and information while making the product. To capitalize on this, Shazop offers a B2B service called Ragtrades, which sells data to retailers to help them handle their pricing and buying methodologies. Marron told Business Insider that Ragtrades' most popular product is a price tracking dashboard.  

Marron knows that online shopping can be troublesome to many. "Finding something that fits you really well is certainly a big concern," Marron said. "And finding something that you love in your size that fits you at the right price."

But Shazop could be appealing to those who have disavowed online shopping.

Marron believes that online shopping and in-store shopping have a symbiotic relationship. In fact, it's partially the basis of Shazop.

"I really see them [in-store shopping and online shopping] as so separate; they both inform each other I’d say," she said. "If you love in-store shopping you can use something like Shazop — say you go tot the store and try something on [and use] a tool like Shazop to find the best price."

But ultimately, when it comes to in-store shopping and then going home to shop online, Marron believes that "the lines are getting blurred."

If Santa was a woman, could she do the job?

Marketing company Anomaly teamed up with RSA Films to ask kids if a woman had what it takes to be Father Christmas. Their answers were an almost unanimous "no." 

"We tested the idea by asking my kids, and their answers were uncomfortably surprising," said Anomaly's Chief Strategy Officer Stuart Smith. "What started as a bit of elfish fun about one issue surfaced another... who and what is shaping our children's gender perceptions?"

Some of the kids' cringeworthy answers were supported by long-held stereotypes about women.

"For one, she would get lost in the sky," one little boy said.

Another little girl feared that a woman Santa may have difficulty balancing her very important career and motherhood. "If she has a baby then she'll be... doing the presents, taking care of the baby, giving it milk," the girl said.

But all hope wasn't lost. One young boy had no doubt that Christmas could be carried out by a heroine.

"Maybe the girl Santa might be one of, like, the strongest ladies in the world," he said. "Girls aren't any different than boys."

Arizona's Antelope Canyon is an incredibly unique natural wonder that draws tourists from all over the world to Arizona.

It's a slot canyon, which means that it was formed by water rushing through rock. The narrow formation has two parts: an upper and lower section, both of which are only accessible by guided tour.

Tours are usually given by people from the Navajo tribe because the canyon sits on Navajo land in Page, Arizona. Although tours are around $25, Antelope Canyon is one of the most-visited slot canyons in the Southwest.

It's easy to see why.

About six years ago, photographer Jenny Lewis posted leaflets throughout London's Hackney borough looking for 10 women who would pose with their newborn baby within 24 hours of giving birth. Her goal: to capture a woman's strength during one of the most intimate times of her life.

Her friends thought her plan was pretty unorthodox.

"My mates were like, 'No one's going to call you, no one's going to want to do it,'" Lewis said of her friends' reactions. "But I got an email and I was like, 'yeah, there we go.'"

When Lewis set out on this journey she didn't know that she would be taking pictures of new mothers for the next five years, nor could she have imagined the amazing stories she would hear.

The whole project, which she thought would be a series of six, maybe 10 photographs for her website, all began out of frustration. "I had two kids and it had gone really well and I probably felt the most empowered and strong I'd ever felt," Lewis said, explaining that everyone else had always focused on the negatives of pregnancy. "All the stories I'd been fed when I was pregnant were like, take all the drugs you can. It's a nightmare, it's painful. Everyone always felt open to share the bad stuff."

Lewis wanted to capture the other side of the story — that odd mix of relief and pride that she felt after giving birth. The project got off to a slow start, but after she photographed and talked to the first few mothers, she decided to expand the project.

"Twenty sounded better. Then I got 20, and I was like 50 will be really good, maybe 100 would be, like, smashing it," Lewis said.

She ended up taking pictures of 150 mothers with their newborns and published a book, "One Day Young."

Lewis has been an editorial photographer for 20 years, taking pictures of famous actors, musicians, and authors, including John Goodman, Dame Maggie Smith, and the Beastie Boys to name a few. But this pet project hit a deeper chord.

"It's just real life," Lewis said. "What was just on my doorstep was more interesting than any pictures I've ever taken."

Because Lewis is invited into the homes of women who have just given birth and who she has never, before that moment, met in person, Lewis bonds with the subjects of her photographs rapidly. She said she remembers each interaction with the mothers she has photographed.

"There's no barrier. So whatever's on their mind comes up," Lewis said. "So I'll have someone telling me they lost their mother when they were two. They didn’t know what a mother is. Now they're being something they never witnessed. That was such an emotional conversation."

 In October, Lewis teamed up with WaterAid to take her project to Malawi. There, she highlighted the challenges mothers face who don't have access to clean water.

"I'd meet women who walked 13 hours to get to the health center, and were nine and a half months pregnant, and they'd wait for two weeks to have the baby," Lewis said.

Despite these mothers living a completely different life than the 150 women featured in her book, Lewis said all the women had something in common during the personal moments she shared with them.

"The emotions on the women's faces and their body language was similar to the women in London," Lewis said of the Malawi mothers. "Because again, what takes over is the primitive. It's the overwhelming joy and relief, the pride in yourself. You know, no one else has done it, you have done it."

With a net worth of $78.9 billion, Microsoft cofounder Bill Gates is the richest man in America.

It shouldn't be too surprising that one of the wealthiest people in the world also has an insanely extravagant home.

It took Gates seven years and $63 million to build his Medina, Washington, estate, named "Xanadu 2.0" after the fictional home of Charles Foster Kane, the title character of "Citizen Kane."

At 66,000 square feet, the home is absolutely massive, and it's loaded to the brim with high-tech details.

He reportedly pays around $1 million in property taxes each year.

Half a million board-feet of lumber was needed to complete the project.

The house was built with 500-year-old Douglas fir trees, and 300 construction workers labored on the home — 100 of whom were electricians.
